Abstract:
This contribution presents the Small Quantum System (SQS) scientific instrument, which is one of six experimental end stations at the European XFEL. This experimental platform is designed for investigations of atomic and molecular systems, as well as clusters, nano-particles and small bio-molecules. It is located behind the SASE 3 soft x-ray undulator, which will provide horizontally polarized FEL radiation in a photon energy range between 260 𝑒𝑉 and 3000 𝑒𝑉 (4.8π‘›π‘š to 0.4π‘›π‘š) with 0.1 to 2 Γ— 1014 photons per pulse and up to 27000 pulses per second. Two high-quality elliptical mirrors in Kirkpatrick-Baez configuration will focus the FEL beam to a FWHM spot size of approximately 1πœ‡π‘š diameter. This is going to result in an intensity of more than 1018π‘Š/π‘π‘š2 within the interaction region, which will allow for studying non-linear multi-photon processes. Furthermore, the short FEL pulse duration between 2 𝑓𝑠 and 100 𝑓𝑠 in combination with a synchronized optical femtosecond laser will enable time-resolved studies of dynamic processes, thus capturing the motion of electrons and nuclei with unprecedented resolution in space on ultrafast time scales.
